mysql_connect($server, $username, $password)or die("koneksi gagal");
mysql_select_db("1evaluasi")or die("database tidak ditemukan");

header ('Content_Type: text/xml');

$kdsoal = $_POST['kdsoal'];

$result=mysql_query($perintah) or die (mysql_error());
$juml_kolom=mysql_num_fields($result);

echo "<?xml version='1.0' ?>";
